AIR SUPPLY FOR TUMBLERS.

Application led November 27, 1925. Serial No. 71,724.

This invention relates to air supply and apparatus therefor for drying receptacles. A articular object of the invention 1s to provide in a drying receptacle, which is par- 5 ticularly adapted for the drying oclothes in laundries and the like, an air supply and means'lfor regulating and directing such air supply to the receptacle so that certain objections will be overcome, which have heretofore appeared in the use of an ordinary hot room or drying room wherein clothes were dried.

A further object of the invention is to prevent in drying` receptacles the quick con- -densation of the steam when the air is drawn from the outside atmosphere and also to do away with the necessity of heatm aI large volu1ne-of air, which is continual y drawn from the outside atmosphere.

'A further object of the invention is to provide a hot air supply for receptacles wherein clothes are dried by passing therethrough a continuous current of warm or hot air to effectively and quickly dry the clothes.

A further object of the invention 1s to provide a device in combination with an air circulation system, which will change the cold air suctlon, which has been heretofore used to a hot air circulation, which more rapidl dries the clothes. l

A fiirther object of the invention is to maintain a constant volume of air flow so that the clothes will be thoroughly dried with a minimum of time and labor.

Referring to the drawings, wherein I have shown a preferred embodiment of my invention,

Fi re 1 is va schematic view showing how the air is treated and passed through a drying receptacle and through the air chamberv forming a part of my invention, the chamber itself being shown in cross-section to show the interior thereof, and a portion of the receptacle being broken away to show the heatmg element and suction device.

Figure 2 is a view in end elevation looking at the left hand end of the air chamber as shown in Fi re 1 and illustrates the position of the air cut-oil or valve. D

Referring to the drawings-in detall, 5 1ndicates in schematic manner a receptacle, such for instance, as a, clothes dryer whlch is used in laundries to dry clothes that have been washed, and through which is assed a current of hot air, the circulation o the air an inlet 9 having formed at the front therei of a housing lO'in which is provided a heater ll of any suitable type. In this instance, one is shown, which comprises electrical coils S0 arranged that they are in the path oi' the air drawn in by the fan 6 through the pipe l2 which opens into the housing 10. The pipe 12 is provided with two branches 13, and 1li:y which are connected to the upper and lower portions of air chamber 15. This air chamber may be of any convenient size and may even be embodied in a whole room.

vThe ends 16 of the chamber 15 are provided with slots 17 inwhich operate the valve plates 18, said plates having suitable opcnlngs therein 19, which control the flow of air through the pipes connected to said chamber. The walls 16 of the chamber are provided with openings 2O and 21, there being formed -in the chamber' 16, compartments 22 from which lead the branch 14 of pipe 12 and the branch 23 of pipe 25. The

branches 13 and 24 respectively of thesev pipes opening directly into the chamber 15. The top and bottom of the chamber is provided with outlets 26 which open out of the compartments 22.

In order tooperate the slide valve 18, I provide an operating lever 27, pivoted as at 28 to the standard 29, which is mounted on top of the chamber 15. It is evident there- :fore that by manipulation of the lever 27 to the position shown in Figure 1, the openings 20 in the chamber 15 will be uncovered and the openings 21 thereof will be closed so that, as shown by the arrow, the air will How through the chamber in the direction toward the inlet side of the receptacle. In order to cleanse this air in its passage through the chamber 15, I provide in the interior of said chamber a pluralit of screens 29 which may be of any materia such as wire nettinor or fabric. Vhen the operating handle 27 is depressed, it will of course close the openings 20 in the chamber and uncover the o enings 21 in the compartments 22 so that t e air will flow to atmosphere, that is, be-l ing forced out of the receptacle and the air lthat is being drawn into the tumbler will be drawn from atmosphere. It is evident that any Achange of air necessary in the receptacle pressed so that the air flowing in pipe 25 isA exhausted to atmosphere and the air drawn in through the pipe 12 is drawn from atmosphere. The heating element 11 is in the path ot the air and heats the air passing therethrough.

The chamber 15 is closed through thev medium of a suitable door 30, which. is suspended from the hook 31 and is secured in position through the medium of the bolts It will be evident therefore that I have arranged a hot air supply to a clothes drying receptacle which will retard the condensation of steam, which took place rapidly inthe old form of receptacle when air was drawn from atmosphere directly into the receptacle, Ithereby wasting the steam. Also, my Aimproved apparatus does away with the heatlng o't a large volume of air by using the heated air over again. The old dryin receptacle used a continuous supply ot' co d air and continually discharged the same after it was heated. My idea overcomes this and thereby economizes in the operation of drying the clothes. The use of my improved air chamber also allows for a flow of a constant volume of air, which aids in rapidly drying the clothes. Also, when fresh air is desired in the receptacle, the same can be had without disturbing the temperature of the hot air in the chamber and my chamber changes the cold-air suction to a hot air circulation, which more rapidly dries the clothes.

Having described my invention, what I claim is 1. The combination with a clothes drying device having an air inlet and an outlet of a chamber through which said air passes in circulation to and from the drying device, adapted to accumulate air and valve members in .each of the end walls of said chamber for divert-ing thel air discharged from said dry-ing device into the chamber or into atmosphere.

2. In a .drying device, the combination of a drying receptacle through which air is adapted to circulate, said receptacle having an air inlet and an outlet, a heating element adjacent said vinlet and a chamber disposed between said inlet and said outlet at a point remote from the receptacle through which the air in circulation -to and from the rev members operable in unison in the end walls v of said chamber, said valve members being provided with openings whereby when they are operated, they close some of said inlets and some of said outlets and av cleanlng element in said chamber through which the I air in circulation is adapted to pass.

, y 15- 4. In a hot air circulation system adapted for use in a cloths drying device, an air,

chamber in connection with said drying device, having inlets and outlets, compartments opening to atmosphere 1n said chamber and valve members between said inlets and said outlets whereby the iiow ot air through said compartments is regulated, and means for operating said valve members in unison.

5. In an air circulating system, comprising a drier having a fan opening in one end thereof, a chamber, the end walls of which are spaced to provide lvalve guide slots, valve members slidable in said slots, the walls of said chamber and said valve members being provided with orifices which match to provide 'openings through the walls of the chamber, compartments in said chamber, each of said compartments having an outlet and a lever for operating said valve members simultaneously whereby the How of air can bediverted through the compartments or through the chamber itself.

6. The combination with a clothes drying system of a housing interposed in said .system for holding a large volume of air necessary for use in drying clothes and valves in the oppositeends' of said housing for diverting the air through the housing or into atmosphere, said valves being operable in unison.

In testimony whereof I affix my signature.
